Description

Note: These are the older style OEM Bosch ignition coils. BMW has since replaced the OEM Ignition Coils with ELDOR

This is the ultimate package to restore your BMW N54 to its full potential. Often times, replacing old spark plugs and ignition coils will lead to a restoration of horsepower and eliminate engine misfires. We recommend replacing your spark plugs and ignition coils before tuning or modifying your N54. On tuned N54’s spark plugs should be replaced every 20,000 miles while ignition coils should be replaced every 35,000-40,000 miles.
